decemberfest.jpgAround September, I thought I should brew an Oktoberfest lager. I never got around to it.

In October, I thought maybe a Novemberfest lager would be a good idea. I never got around to it.

In November, I thought maybe a Decemberfest lager would work. I never really got around to it until mid-December.

It probably won't be ready to drink before January, but I thought I could still call it Decemberfest as I was brewing it in December. And ... I might drink some of it before the end of the year.

Rather than the Marzen style, I went with more of a "Festbier". My first attempt at this style.

Batch #1 of this beer was my 6th batch that I brewed on my Anvil Foundry. 

This is one of those beers that both the Brew Master and the Beer Model like.

It is a beautiful golden lager. Not too light. Not too heavy. 

Not too malty. Not too hoppy.

Not too sweet. Not too bitter.

Just an awesome easy drinking lager. At 5.5% ABV, it isn't sessionable, but at the same time, it isn't a beer that will mess you up if you drink one or two.

Pretty much a beer-drinker's beer.

Making yeast starter out of trub I collected from Schreck Gartenzwerg Pilsner. Brew day tomorrow. Looks like it will be a cold one. 
12/14/2020 esheppy
Brew day went well yesterday. My OG was a little low, but that's ok. 1.052. This morning, the fermentation is going at 51 degrees. Set the Anvil temperature controller to 52. 
12/15/2020 esheppy
Tilt says 1.042 at 52. Setting temp to 53. 
12/16/2020 esheppy
Tile says 1.031 at 54. Moving the temp up to 54. Bubbling still pretty active. 
12/17/2020 esheppy
Tilt says 1.022 at 55, which is the Anvil set point right now. I'll probably set to 56 before the end of the day. Tomorrow, I'll probably turn off temp control completely. 
12/18/2020 esheppy
1.015 57. Still bubbling pretty good. 
12/19/2020 esheppy
Tilt says 1.013 at 59. Turned up temp to 62. 
12/20/2020 esheppy
Tilt says 1.011 at 62. Unplugged pump. 
12/22/2020 esheppy
Tilt says 1.010 at 67. Not much bubbling. I think this is pretty much done fermenting. I don't have an empty keg, but I think I will soon. The plan is to keg the 26th. 
12/23/2020 esheppy
Took a little sample. Cloudy but nice flavor. 1.010 at 67. 
12/27/2020 esheppy
Kegged. FG 1.010. Nice golden color. Pretty simple lager profile. None of the heavy caramel or Munich flavors of a marzen Just a touch of Hallertau hops in the finish. I think we're really going to enjoy this beer. 
12/29/2020 esheppy
Added gelatin to the keg. Hit with more CO2 
12/31/2020 esheppy
Clarity getting pretty good. Color gorgeous gold. Delicious beer. Just needs more carbonation. 
01/01/2021 esheppy
Officially ready to drink. The Beer Model declared it "yummers". Nice malty lager. Really like the Vienna malt flavor. 
01/03/2021 esheppy
Beer drinking this a bunch. Beautiful golden lager. Nice clarity. Carbonation right there. Really delicious. Easily consumed by the liter. 
01/15/2021 esheppy
Great beer. Both the Beer Model and I love it. Nice clear golden color. Carbonation about perfect. Great vienna malt flavor. Just enough bitterness to balance the malt. Nice floral Hallertau hop in the finish. Wonderful.

Keg blew tonight. It was a wonderful beer while it lasted.
